PRIORITY CLAIM

This application is a continuation application from U.S. application Ser. No. 16/454,764, filed Jun. 27, 2019, which is a continuation application from U.S. application Ser. No. 15/450,290, filed Mar. 6, 2017, which is a divisional application of U.S. application Ser. No. 14/186,051, both of which claim priority to U.S. provisional patent application Ser. No. 61/768,766, filed Feb. 25, 2013, the entire contents all of which are incorporated herein by reference and relied upon.

FIELD

The present disclosure relates generally to the field of cookware. More particularly, the present disclosure relates to solutions for leveling cookware with a flat cooking surface. By way of non-limiting example, the present disclosure can be applied to level frying pans, skillets, and griddles and on gas or electric stovetops.

BACKGROUND

Many people cook with oil or melted butter. In order to most effectively cook with oil or melted butter, a level cooking surface is preferred. If the cookware does not set on the stovetop such that the cooking surface remains level, then the cooking oil or melted butter will naturally leak to the lower side of the cooking surface. This requires constant shifting of the cookware by the chef in order to make sure the cooking oil or melted butter coats the entire cooking surface. If constant attention is not given, the cooking oil or melted butter will not evenly coat the cooking surface or the food being prepared.

SUMMARY

In an embodiment of the present disclosure, the problems of the prior art are overcome by including a detachable adjustable leg that can attach to the cookware. The leg adjusts to level the surface of the cookware. In one embodiment, the at least one detachable adjustable leg makes contact with the stovetop to tilt the cooking surface in order to make it level. The adjustable leg can be used to increase pressure on the stovetop, thereby increasing the tilt until the cooking surface is level. Multiple adjustable legs can be used to increase stability and accuracy. In another preferred embodiment, the at least one detachable adjustable leg is weighted at one end and the weighted end extends outward in order to make the cooking surface level. Multiple adjustable legs can be used to increase the stability and accuracy. In yet another embodiment, the cookware comes with at least one adjustable leg permanently attached for leveling.

The adjustable leg, detachable or permanent, can be made from any material able to withstand close proximity to a stovetop flame. The embodiments described herein can be applied to cookware being used on a gas stovetop or an electric stovetop or any cooking surface on which a level cooking surface is desired. The detachable adjustable legs can be designed to be secured to any cookware.

In another embodiment, the leveling of the cookware is accomplished by adjusting the surface of a grate that is typically used with gas stoves. The surface of the grate is adjustable by, for example, simply twisting legs on the top or bottom surface of the grate. Twisting legs on the bottom of the grate, such that the length that the leg protrudes from the bottom surface of the grate is altered, changes the tilt of the top surface of the grate. Alternatively, legs can be installed on the top surface of the grate such that the cookware rests on the legs. Adjusting the length that the legs protrude from the top surface of the grate changes the tilt of the cooking surface and therefore can be used to level the cooking surface. This embodiment can also be used with a grate configured to be used with an electric stove.

DETAILED DESCRIPTION

An embodiment of the present disclosure relates to a leveling the cooking surface of cookware. FIGS. 1A-1C show prior art cooking pans. FIG. 1A shows a prior art skillet or frying pan 100. As sold, the prior art skillet 100 typically includes a level cooking surface 101. The skillet 100 also includes a side wall 102 and a handle 103. FIGS. 1B and 1C show a prior art griddle 120. As sold, the prior art griddle 120 typically includes a level cooking surface. The griddle 120 can include a flat level cooking surface 121 as shown in FIG. 1B or a ribbed level cooking surface 122 as shown in FIG. 1C. As used herein, the term “flat cooking surface” comprises flat level cooking surfaces, ribbed level cooking surfaces, as well as cooking surfaces that are partially or totally warped such that they are not entirely level. A person of ordinary skill in the art will recognize that other prior art cookware includes a flat cooking surface and the disclosed embodiments that follow can be applied to that other prior art cookware.

FIGS. 2A-2I show a first embodiment of a detachable adjustable leg stabilizer. FIG. 2A shows a detachable adjustable leg stabilizer 200. The detachable adjustable leg stabilizer 200 includes a clamp 201 for attaching to the rim of the cookware at a first end. The clamp 201 can be magnetized. The second end 203 of the detachable adjustable leg stabilizer 200 is capable of making contact with the stove surface. The second end 203 can be a flat piece for greater stability or can be a pointed end. The second end 203 can magnetized. The second end 203 can also be made of rubber or another material, including materials that increase friction between the second end 203 and the stove surface. The second end 203 of the adjustable leg 202 can be part of the adjustable leg 202 or can be a separate piece that is attached to the adjustable leg 202. The adjustable leg 202 is a rigid material. The adjustable leg 202 allows the distance between the first end 201 and the second end 203 to increase or decrease. The adjustable leg 202 does not have to change length. The adjustable leg 202 is used to allow the first end 201 to change positions relative to the second end 203 and that is what is meant by adjusting the adjustable leg 202. One method of adjusting the adjustable leg 202, shown in FIG. 2A, is a handle 204 that can twist to move the adjustable leg 202 in a screw-like fashion to apply angular pressure on the stove surface. The adjustable leg 202 of FIG. 2A is threaded and passes through a similarly threaded portion connected to the clamp 201. By twisting the adjustable leg 202, the adjustable leg 202 passes through the threaded portion connected to the clamp such that the second end 203 of the adjustable leg 202 moves closer or further from the threaded portion.

FIG. 2B shows a side view of the detachable adjustable leg stabilizer of FIG. 2A with an extender arm 205. The extender arm 205 is positioned substantially parallel to the stove surface such that the adjustable leg 202 pushes on the stove top from a more vertical alignment, causing downward pressure. The extender arm 205 can be threaded so that the adjustable leg 202 passes through it and allows the distance between the extender arm 205 and the second end 203 to be increased or decreased.

FIG. 2C shows another design for the clamp 201. The design shown in FIG. 2C works similar to a clothes-pin. Squeezing the top end of the clamp 201 shown in FIG. 2C will open the legs on the lower end. Releasing the top end of the clamp 201 shown in FIG. 2C will cause the lower end of the clamp 201 to tighten on the rim of the cookware. The adjustable leg 202 can be threaded through hole 210 shown in FIG. 2C, which is itself similarly threaded.

FIG. 2D shows another design for the adjustable leg 202. The adjustable leg 202 of FIG. 2D includes buttons 220 that can be depressed, but without pressure will pop back up to their original position. By pushing the buttons in and sliding the adjustable leg 202 the adjustable leg 202 will move in position. On the clamp 201 (not shown here) the hole for the adjustable leg 202 will fit snug on the adjustable leg 202 such that the adjustable leg 202 can move through the hole when a button is depressed, but the adjustable leg 202 cannot move if a button is not depressed. Once the desired position is reached, the button can be released and the adjustable leg 202 will be locked in place. One skilled in the art will appreciate that there are other variations regarding how to lock the clamp 201 in position along the adjustable leg 202 that are well-known in the art.

FIGS. 2E-2I show different designs for the second end 203 of the adjustable leg 202. FIG. 2E shows a simple rigid design for the second end 203 of the adjustable leg 202. The rigid design can be a flat surface or can be a rounded surface. FIG. 2E shows a flat surface. A flat surface should be designed to be flush to the stove surface when in use. A rounded surface will also work as long as it does not slip on the stove surface. The adjustable leg 202 may fit with the second end 203 on an angle or vertically, depending on whether the extender arm 205 is being used. FIG. 2F shows a second end 203 of the adjustable leg 202 that is flexible. The flexible second end 203 allows the adjustable leg 202 to always stay flush to the stove surface while allowing the adjustable leg 202 to change angles relative to the stove surface. FIG. 2F shows a simple hinge design, although other designs that accomplish the same flexibility are well-known in the art. FIG. 2G demonstrates that the second end 203 of the adjustable leg 202 can be multi-prong. A two-prong second end 203 is shown, but a person of ordinary skill in the art will recognize that any number of prongs is possible. FIG. 2H demonstrates that the second end 203 of the adjustable leg 202 can be magnetized for better stability with the stove surface by simply fastening a magnet 230 to the bottom surface of the second end 203. A person of ordinary skill in the art will recognize that any of the designs for the second end 203 can be magnetized. FIG. 2I demonstrates that the second end 203 of the adjustable leg 202 can include a ribbed underside for better grip to the stove surface. The ribbed underside can be made of metal, rubber, or any material that increase the grip between the second end 203 and the stove surface.

FIG. 3A shows a second embodiment 300 of the present disclosure. The adjustable leg 202 in the second embodiment extends outwards from the cookware, but does not contact the stove surface. Rather, the second end 303 of the adjustable leg 202 extending outward from the cookware causes the cooking surface to shift in the direction of the second end 303 of the adjustable leg 202. Extending the second end 303 outward causes a greater force to be exerted on the cookware in the direction of the second end 303. A person having ordinary skill in the art will recognize that the adjustable leg 202 can be designed in any of the ways described in connection with the first embodiment 200. Another variation on this embodiment is using a non-adjustable leg. FIG. 3B shows a first design for the second end 303 of the adjustable leg 202. The second end 303 shown in FIG. 3B is a solid weighted end. The solid weighted end can made of the same material of the adjustable leg 202 or can be a different material. FIG. 3C shows a top, side and cross-section view of a second design for the second end 303 of the adjustable leg 202. The second end 303 shown in FIG. 3C is basket-like such that the weight of the second end 303 can be adjusted by adding weights to the basket. The basket must face upwards so that weights can be added to the basket. To make sure that the basket will face up if a screw-like adjustable leg 202 is used, the basket can be threaded, as shown in the cross-section view, so that it can also be twisted to always face upwards. The weights added to the basket can be ball bearings or water or any suitable material. A person having ordinary skill in the art will recognize that anything that fits into to the basket can serve to weight the second end 303.

In a third embodiment 400 of the present disclosure, at least one adjustable leg stabilizer is permanently incorporated into the cookware. FIG. 4 shows a third embodiment 400 of the present disclosure that is comparable to the first embodiment, except that instead of a detachable clamp 201, the one or more adjustable leg stabilizers 202 is permanently attached to the cookware at a first end 201. The adjustable leg 202 can be threaded through a threaded hole in the side wall 102 of the cookware. As will be appreciated by those skilled in the art, any described design for the adjustable leg 202 or the second end 203 is possible. And the third embodiment 400 can easily be adapted by using the extender arm 205 of FIG. 2B. As will further be appreciated, one or more permanent adjustable legs can be used with one or more detachable adjustable leg stabilizers to increase the accuracy and stability. As is shown in FIG. 4, the adjustable legs 202 are arranged in a triangle fashion. Those skilled in the art, however, will appreciate that any number of adjustable legs 202 can be used in any number of configurations. Further, FIG. 4 shows the threaded holes in the side wall 102 of the cookware. But the sidewall 102 can be extended upwards where the adjustable legs 202 are positioned as to keep the original sidewall intact.

FIG. 5 shows a fourth embodiment 500 of the present disclosure. As with the third embodiment 400, the fourth embodiment 500 includes at least one adjustable leg stabilizer permanently incorporated into the cookware at a first end 201. FIG. 5 shows a fourth embodiment 500 of the present disclosure that is further comparable to the second embodiment in that the adjustable leg extends outward from the cookware. FIG. 5 includes one or more screw-like adjustable legs 202 for extending the adjustable legs 202 outward from the cookware. The adjustable leg 202 can be threaded through a threaded hole in the side wall 102 of the cookware. The second end 303 is comparable to the second end 303 described in connection with the second embodiment. As will be appreciated by those skilled in the art, any described design for the adjustable legs 202 or the second end 303 is possible. Another variation on this embodiment is to use a non-adjustable leg and the basket-like second end 303 as shown in FIG. 3C. As will further be appreciated, one or more single permanent adjustable legs can be used with one or more detachable adjustable leg stabilizers to increase the accuracy and stability. As is shown in FIG. 5, the adjustable legs 202 are arranged in a triangle fashion. Those skilled in the art, however, will appreciate that any number of adjustable legs 202 can be used in any number of configurations. Further, FIG. 5 shows the threaded holes in the side wall 102 of the cookware. But the sidewall 102 can be extended upwards where the adjustable legs 202 are positioned as to keep the original sidewall 102 intact.

In a fifth embodiment of the present disclosure, the leveling of the flat cooking surface is accomplished by adjusting protruding legs 602 on a grate 600 that typically sits over a gas stove. FIG. 6A shows an exemplary grate 600 with adjustable legs 602 on the top surface. The design of the grate 600 is only by way of non-limiting example, as many different designs within the scope of the present disclosure will accomplish the same result. This embodiment can also be used with a grate configured to be used with an electric stove. The cookware sets on the adjustable legs 602. The adjustable legs 602 protrude from the top surface and are adjustable, for example, by twisting them. The grate 600 can have threaded holes 604, as shown in FIG. 6A. Alternatively, one or more blocks, each having a threaded hole that mates with the adjustable legs 602, can be fastened to the top of a grate with no threaded holes. The adjustable legs 602 can be threaded such that twisting them causes the adjustable legs 602 to protrude more or less from the top surface of the grate 600. The top end 603 of the adjustable legs 602 that makes contact with the cookware can be rounded, flat, or any design that allows the cookware to stably set on the adjustable legs 602. Only two adjustable legs 602 are shown in FIG. 6A but a person of ordinary skill will recognize that any number of adjustable legs 602 can be used.

In FIG. 6B the adjustable legs 602 protrude from the bottom surface of the grate 600. In FIG. 6B, the adjustable legs 602 are in direct contact with the stove surface. The adjustable legs 602 protrude from the bottom surface and are adjustable, for example, by twisting them. The adjustable legs 602 can be threaded such that twisting them causes the adjustable legs 602 to protrude more or less from the bottom surface of the grate 600. As such, adjusting the length that the adjustable legs 602 protrude from the bottom surface of the grate 600 causes the tilt of the top surface of the grate 600 to change. The grate 600 can have threaded holes on the bottom surface. Alternatively, one or more blocks, each having a threaded hole that mates with the adjustable legs 602, can be fastened to the bottom of a grate with no threaded holes. The second end 610 of the adjustable legs 602 that makes contact with the stove surface can be rounded, flat, or any design that allows the grate to stably set on the stove surface. The design of the second end 610 of the adjustable legs 602 can be designed in any of the ways described in FIGS. 2E-2I.

In FIG. 6C the adjustable legs 602 are represented as circles on the bottom of grate 600. FIG. 6C shows the same configuration as FIG. 6B but from a different angle. The perspective is shown as looking straight down on the bottom side of grate 600.
